Houses get rained on all the time while being built but why is there no continuing mold problem after this?

They dry out. Once you wrap the frame in a weather barrier like Tyvek, install the windows… that prevents the inside from getting wet while any residual moisture is able to dry quickly before the drywall goes up.. It only becomes moldy when moisture/dampness festers for a long time. A few days or rain and then it drying out quickly isn’t enough for that to happen.
